From 4d9d3f164de7002dd38f12dc40f9b260f63d2d9b Mon Sep 17 00:00:00 2001 From: Aamir Bohra Date: Mon, 9 Dec 2019 16:05:52 +0530 Subject: soc/intel/cannonlake: Allow Audio DSP OSC qualification for low power idle With Audio DSP OSC qualification disabled from S0ix criteria. S0ix is achieved before the DSP is suspended. When driver tries to suspend DSP its already turned off.
